Last night (exactly 24 hours ago) I had a heavy nose bleed. I didn't think twice about it because it wasn't that bad. It lasted about 5 minutes and then diminished. However today, while at the pool, I got a REALLY bad bloody nose. I was not picking my nose, I was not hit, and I am most definitely not allergic to chlorine or anything in the pool. I also have not been taking any kind of medication at all. The nose bleed today lasted a good 10 minutes and I bled A LOT. By a lot I mean I it was a constant flow for 5 minutes and then a steady drip for the last 5 minutes. Finally it stopped.
What could be other occurrences for this? I used to get a lot of bloody noses as a child, but back then I picked my nose. Now, I do not. Suggestions?
